Text-to-Speech MP3 and WAV Converter
Generate speech once, then download the same completed result as WAV or MP3—free, with no account, payment details, or API key required. Choose WAV when you plan to edit or re-encode the audio, or MP3 when the destination accepts it and a smaller file is more practical. The current WAV export is mono, uncompressed 16-bit PCM at 44.1 kHz. The current MP3 export is created from that WAV in your browser as mono, 44.1 kHz audio using lossy encoding configured for a constant bitrate of 96 kbps. Completed batches can be downloaded as WAV or MP3 ZIP archives.

Benefits
One Generation, Two Download Options
Both formats begin with the same completed synthesis. Download the browser-created WAV or convert that same WAV to MP3 without uploading the audio to a remote encoding service.
An Uncompressed WAV Source for Editing
WAV stores the generated audio as one-channel, 16-bit PCM at 44.1 kHz, giving you an uncompressed source before further editing or encoding.
A Smaller MP3 Option for Delivery
MP3 uses lossy encoding with a 96 kbps constant-bitrate setting and is usually smaller than WAV for ordinary narration clips.
Individual Files or Batch ZIPs
Download one result directly, or package completed batch clips as separate WAV or MP3 files inside a ZIP archive.
How To
- 1
Enter Text or Prepare a Batch
Type or paste your text and follow the live limit shown in the tool. To create one file per line, open “File & Batch Options,” enable separate audio files, and follow the displayed batch limits.
- 2
Choose a Language and Preset Voice
Select from the language and voice options shown for your current browser session, then adjust the speed and generation quality if needed.
- 3
Generate and Review the Speech
Start the AI Voice Engine, select “Generate Speech” or “Generate Batch,” and listen for wording, pronunciation, pacing, silence, and unintended changes before downloading.
- 4
Choose WAV or MP3
Download WAV when you want an uncompressed source for further work. Choose MP3 when the destination accepts it and a smaller lossy file is more practical. For a completed batch, choose the WAV or MP3 batch download; the browser packages the individual files as a ZIP archive.
- 5
Check the Saved File Where You Will Use It
Import the file into its intended editor, player, or platform. Confirm playback, timing, level, and format support, and keep the WAV when later revisions or another encode are likely.
Tips
- Keep WAV when you expect to trim, process, mix, or re-encode the narration.
- Use MP3 for review or delivery when the destination accepts it and a smaller file is more useful than an uncompressed source.
- Include sequence and revision information in batch filenames. Use the `{text}` token only when part of the script is appropriate for a filename and does not expose sensitive information.
- Listen before downloading, then spot-check the saved file in the editor, player, or platform that will actually use it.
Limitations
MP3 Is a Lossy Copy
The browser creates MP3 from the completed WAV PCM and discards information during encoding. Keep WAV when further editing or another encode makes an uncompressed source useful.
File Size Depends Mainly on Duration
At the current fixed format settings, duration determines most of the size difference. Container overhead and encoder output affect the exact result, so ttsgenerator.com does not promise a fixed MP3-to-WAV size ratio.
Both Outputs Are Mono
The current WAV and its derived MP3 contain one audio channel. Stereo placement, music, effects, or a wider mix must be created later in an editor.
Browser and Batch Limits Still Apply
Follow the live text, file-count, and generated-audio limits shown in the tool. ZIP packaging groups completed files into one archive; it does not combine them into one recording, change their audio format, or apply another audio-encoding step.
Frequently Asked Questions
What exactly is the current WAV output?
The current WAV export is a RIFF/WAVE file containing mono, uncompressed 16-bit integer PCM at 44.1 kHz. In batch mode, placing completed WAV files in a ZIP does not change the format of each audio file.
What exactly is the current MP3 output?
The current MP3 export is created in your browser from the completed mono WAV at 44.1 kHz, using lossy encoding configured for a constant bitrate of 96 kbps. A single result downloads as one MP3, while completed batch MP3 files are packaged in a ZIP.
What sample rate is used?
Both current export formats use a 44.1 kHz sample rate. Choosing MP3 does not change the sample rate, although MP3 applies lossy compression.
Should I choose WAV or MP3?
Choose WAV when you expect further editing, processing, mixing, or re-encoding. Choose MP3 when the destination accepts it and a smaller delivery or review file is more practical. Check the destination’s current format requirements before deciding.
How much smaller is MP3?
At the current settings, one minute of audio is approximately 5.3 MB as mono 16-bit PCM WAV and 0.7 MB as 96 kbps MP3, before small container or encoder overhead. Actual file size varies with duration and overhead, so ttsgenerator.com does not promise a fixed ratio.
Does MP3 conversion upload my audio?
No. When you request MP3, your browser loads the MP3 encoder if needed and converts the completed WAV locally. Loading the encoder still uses a network request, but that request does not include your generated audio.
Can I use WAV and MP3 files generated with ttsgenerator.com commercially?
Yes. Audio generated with ttsgenerator.com can be used commercially in either WAV or MP3 format. Changing the file format does not change the applicable rights or restrictions. Follow the applicable Supertonic OpenRAIL-M use restrictions, clearly disclose that the audio is machine-generated, use only scripts and other materials you have the right to use, and follow applicable law and platform rules.
Where are the encoder licenses and source details?
The Licenses page documents the shipped MP3 encoder package, WebAssembly artifact, wrapper, embedded LAME component, model licenses, and browser-runtime notices.
Choose WAV for Editing or MP3 for Delivery
| Your next task | Start with | Why |
|---|---|---|
| Continue editing or re-encode the audio | WAV | It stores the generated narration as one-channel, uncompressed 16-bit PCM at the current 44.1 kHz sample rate. |
| Send a smaller review or delivery file | MP3 | The 96 kbps constant-bitrate file is usually smaller for ordinary narration; confirm that the destination accepts it. |
| Export several separately named clips | Batch WAV or Batch MP3 | The browser packages completed files into a ZIP while keeping each clip as an individual WAV or MP3. |
Both downloads come from the same completed synthesis, but MP3 does not preserve the PCM samples exactly because it uses lossy compression. Choosing WAV or MP3 changes the storage and compression format; it does not change the commercial-use conditions, third-party rights, or platform rules that apply to the content.
When the narration is finished but the audience still needs visuals, captions, and a video export, turn the audio into a video. The provider-neutral video guide covers preparation and timeline checks first. See Licenses for the model, runtime, and MP3 encoder provenance.
